Cryopreservation and in vitro culture of caprine preantral follicles
Reproduction, Fertility and Development, 2011Preantral follicles (PFs) form a far larger oocyte reservoir (∼90% of the follicular population) than antral follicles. Several laboratories have focussed efforts on cryopreservation and in vitro culture (IVC) of PFs to obtain large numbers of fertilisable oocytes.

Isolation and long-term culture of human preantral follicles
Fertility and Sterility, 1993To isolate intact preantral follicles from the human ovary for in vitro studies.Premenopausal human ovary was digested by a mixture of collagenase and deoxyribonuclease (DNase) for 1 hour at 37 degrees C and for 36 hour at 4 degrees C. Intact preantral follicles at classes 1 and 2 were isolated and cultured for up to 120 hours in a serum-free Dulbecco ...

In vitro culture of buffalo (Bubalus bubalis) preantral follicles
Theriogenology, 2002Growth of buffalo preantral follicles in culture was studied to investigate the effect of size of preantral follicles, individual or group culture, long-term culture of preantral follicles for (40 days), addition of human follicle stimulating hormone (FSH), insulin-transferrin-selenium (ITS), growth factors (epidermal growth factor (EGF), fibroblast ...

Morphogenetic reaggregation and luteinization of mouse preantral follicle cells
American Journal of Anatomy, 1979AbstractSmall (60‐90 μm) and large (100‐130 μm) preantral follicles were isolated from adult mouse ovaries by a collagenase‐dissection technique. These follicles were composed of resting oocytes surrounded either by granulosa cells, only, or by granulosa and undifferentiated theca cells.

In-vivo and in-vitro development of preantral follicles
Theriogenology, 1997Abstract This paper presents the state of the art concerning the in vitro growth and differentiation of preantral follicles, i.e. from the primordial to the antral stage, in mammals. Attention is paid to their normal structure and development, nomenclature, isolation and culture methods, effects of systemic and local compounds on their development ...
